Wolfgang Dworazik 1970 Porsche 914-6 Factory M471 - sn 914.043.0919
According to the current owner, this Porsche 914-6 GT, chassis #9140430919, as best as can be pieced together, is a "M-471" option 914-6 built by a German dealer in collaboration with Wolfgang Dworazik, the first owner (a Porsche engineer/tech'n at the time)... https://pbase.com/9146gt/image/25793063
I found a bunch of early photos and am digitizing them now; several of the car in 1974 in Germany just after my brother bought it and several of the thing stripped for restoration in 1981-2
